Natural teas for taking off the effects of drink and process for the production thereof

ABSTRACT

Natural teas for taking off the effects of drink and getting rid of or curing the hangover. The teas can be prepared by using as the main raw materials extracts of leaves, stems or roots of alder and mountain ash or powders obtained by direct pulverization of leaves, stems or roots thereof, and optionally mixing the above extracts or powders with antidotal crude herb medicines including an extract of fructus ligustic fruit and an extract of radix puerariae at various mixing ratios. The effects of the teas for curing hangover are produced by taking the teas before or after drinking.

TECHNICAL FIELD

The present invention relates to natural teas for taking off the effectsof drink and getting rid of or curing the so-called hangover andprocesses for preparing the same, and more particularly to natural teascomprising essentially extracts from alder and mountain ash(Sorbuscommixta Hedl.) as well as processes for obtaining the teas.

BACKGROUND OF THE INVENTION

The inventors were interested in making natural and vegetal preparationsfor curing the hangover. After several tens of tests by using alders andmountain ashes, growing in Sosan, a region in Korea, inventors succeededin making natural teas consisting of only vegetal ingredients, which arecapable of curing the hangover, when taken before or after takingalcoholic drinks. The teas according to the present invention includeextracts coming from leaves, stems, or roots of alder and mountain ashand further extracts coming from herb medicines being known to havefunctions of protecting the liver in the human body or detoxicating.

The hangover or the aftereffects of the heavy drink is thought to beinfluenced by toxic ethyl alcohols and/or acetaldehydes beingaccumulated in the liver from heavy alcoholic drinking. The hangovercontinues for hours due to the harmful effect of toxic ethyl alcoholand/or aldehyde on the liver, which causes the metabolism of the body tobe deactivated, resulting in fatigue and exhaustion feeling of the wholebody, feeling of having gas in the vowels, and vomiting.

Under a normal metabolism relating to ethyl alcohols in human body, theethyl alcohols are absorbed into the stomach or the small intestines andthereafter, transferred to the liver through blood vessels. Alcoholdehydrogenase in the liver cells catalyzes the oxidation of ethylalcohols to acetaldehydes, which in turn are decomposed into aceticacids by acetaldehyde dehydrogenase in the same cells. The resultingacetic acids are transferred to muscle and adipose tissues of the bodyand eventually converted to CO₂ and H₂ O. Further, there are two typesof acetaldehyde dehydrogenases: I--type one catalyzing the oxidationprocess of low concentrations of acetaldehydes and II--type one startingto activate the oxidation process only on high concentrations ofacetaldehydes. Unfortunately, it is usual that Oriental people arelacking or short of the II--type acetaldehyde dehydrogenases andaccordingly the oxidation of acetaldehydes is not so well activated thatacetaldehydes and/or ethyl alcohols may not be decomposed and remain inthe liver. The acetaldehydes and/or ethyl alcohols exceedinglyaccumulated in the liver disturb the normal metabolism and result inhangover. For diminishing or curing hangover, some herb or chemicalmedicines have been evaluated and used individually or in a group forhangover cure drinks.

A variety of herb medicines have been used for curing hangover and manyliquid cures including such herb medicines are on the market. Thosedrinks may be taken alone before or after drinking, or mixed with strongalcoholic drinks to be taken. However, those beverages have someproblems: one is to do more harm than good for curing the fatigue,feeling of having gas in the vowels, vomiting, or stomachache, and theother is the high price owing to the expensive medicinal herbs containedtherein.

An object of the present invention is to provide natural teas orbeverages which are capable of curing the hangover.

Another object of the present invention is to provide such hangover curedrinks with a low price.

DISCLOSURE OF INVENTION

The above objects are accomplished by providing natural teas (powderedor liquid) which consist mainly of extracts coming from the leaves,stems, or roots of alder and mountain ash, with extracts of fructusligustri fruits and/or radix puerariae and/or gourds optionally mixedtherein and precesses for preparing such natural teas.

Alders used for the present invention grow in low and moist places orvalleys of mountains, or around small streams and their leaves, stems orroots are known to be rich in tannin being effective for protecting thestomach mucosa. Mountain ashes grow in a deep valley and their leavesand fruits contain a lot of Vitamin C, amino acids and carotenes.Extracts of mountain ashes are known to be good for scorbutus resultingfrom lacking of Vitamins and specifically the beta-carotene has theeffect of clearing up cough and phlegm. Fructus ligustri fruits areeffective for protecting the liver and the stomach.

In addition, extracts of radix puerariae may be added to improve theefficacy of curing hangover by the natural teas according to the presentinvention. Radix puerariae, a sweet and herbaceous vegetable, is knownto have such functions that it helps patients recover from headache, andknown to have excellent detoxicating functions by virtue of glycyrrhizintherein. Further, extracts of gourds may also be mixed in the naturalteas of the present invention and ingredients thereof are said to workwonders on stimulation of urination.

As described above, medicinal properties of the respective vegetalingredients used in the present invention are already known to thepublic. However, particular mixtures of those ingredients are believedto show remarkable synergistic effects. According to the presentinvention, for example, extracts of leaves, stems, or roots of alder arebelieved to strongly take part in the decomposition process of ethylalcohols and/or acetaldehydes when extracts of leaves, stems, or rootsof mountain ash are mixed therewith. Furthermore, extracts of mountainash are believed to provide a supplement of Vitamin C which is apt to beinsufficient due to consumption in the course of oxidation of ethylalcohols, and specifically to contribute to removal of hangover byvirtue of asparagine contained therein.

The various parameters of the technical processes described above areprovided by way of examples and are not restrictive. For example,ordinary extraction by maceration in the above examples 1-36 may beconducted at low or high temperatures. When the extraction is carriedout at the low temperatures of 30° C.-80° C., the time of maceration mayvary from 1 hour to 10 hours. Also, the extraction by maceration may beconducted at high temperatures below 150° C. with the pressure of 2-3atm. Though the 30% ethyl alcohol was used as an extractant, pure wateror 10-70% ethyl alcohols may be used as a substitute on the sameconditions. Furthermore, powders directly pulverized from leaves, stems,or roots of alders, mountain ashes, fructus ligustri fruits and radixpuerariaes may be used as substitutes for extractive powders in thecorresponding preparation steps of natural teas in the above examples.Also, some herb medicines such as jujubes or licorice roots may be addedinto natural teas prepared in the examples 1-36 for improving sweettastes of natural teas according to the present invention. Some steps,for example, concentrating of extracts, may be included in the processesdescribed in the examples 1-36 and thus, more raw materials than in caseof making extractive powders can be disposed.

According to the tests made, the inventors confirmed that respectiveextracts of leaves, stems, or roots of alder or mountain ash show almostthe same effects on curing the hangover and that the efficacy of theteas of the present invention has little with the specific parts ofalder or mountain ash.
